A dry or cracked solder joint increases electrical resistance at the pad level. This resistive hotspot can melt the plastic encapsulation of the HSP06F1S4. Fix: Reflow the solder and inspect under magnification.
Using a power adapter with incorrect voltage can cause the internal voltage regulators to work harder and generate excess heat. hsp06f1s4 hot
